This is Solar Power World’s 2025 list of Top Solar + Storage Installers. Those companies included on the 2025 Top Solar + Storage Installers List provided Solar Power World with a list of storage installations in addition to their solar projects completed in 2024. While the main Top Solar Contractors List ranks companies based on solar kilowatts (kW) installed in the previous year, the Top Solar + Storage Installers List ranks companies based on total storage kilowatt-hour (kWh) capacity installed in the previous year. These storage projects could be completed across all markets (residential, commercial, community solar, utility) and by solar installation companies participating in all services (EPC, developer, solar installer, installation subcontractor, electrical subcontractor, sales partner). The solar + storage projects represented on the list could come in many forms: lithium, lead-acid, flow batteries and more.
The companies below are a segmented portion of the overall 2025 Top Solar Contractors List, organized by kilowatts (DC) installed in 2024.
